Neither option is "good" or "bad".  It's a tradeoff between performance
(binary only driver) and reliability/debuggability/freedom (open source
driver).

It's almost certain that you'll get higher frame rates with the closed
source driver, as the vendor knows all the secret details of the
hardware.

You can check whether 3D acceleration is working with:

$ glxinfo | grep direct

If you see:

direct rendering: Yes

then HW acceleration is working.
